Application am um 2a. 1892.

zen of the United States, residing at Newark,

in the county of Essex and State of New Jersey,

5 have invented certain newand usefulImprovements in Vanishing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apro pertains to make and use the same, reference being had to the accompanying drawings, and

to letters of reference marked thereon, which form apart of this specification. j

The purpose of this invention is to provide 1 5 an improved machine for varnishing or paint ing tin or other material, which is of, simple construct-ion and which will apply the coats of varnish or paint to the material to bevarnished without necessitating any special preparation, and avoiding all waste.

The invention is further designed to more evenly distribute the daub or paint over the surface of the material, such as sheet tin, to

treat the same-so that it is under the perfect 2 control of the operator,- to cut the sheet tin into pieces of the 'proper size and to punch the same and to so handle the sheet metal pieces that they are discharged in 'a finished condition from the machine ready to be laid 0 out for drying.

The invention therefore consists .of certain novel arrangements and combinations of parts, such as will be hereinafter more fully described and finally embodied in the 5 clauses of the claim.

In the accompanying sheets of drawings, in

which is illustrated a machine adapted to carry out the principles of my invention, Figure 1 is a plan view of the said machine. Fig. 2 4.0 is a vertical longitudinal section of the same taken on linew, showing the supporting frame and the bearings for the several distributing rolls in side elevation. ,Figs. 3 and 4 are the two side elevations of the machine, and Fig. 5 5 is a vertical section of the machine taken'on the central longitudinal axis thereof in the plan in Fig. 1. Fig. 6' is an enlarged view of ,the cutter and punching rolls shown, partly in section and partly in elevation, and Fig. 7 5c is a vertical section of the same taken on line 8.5.1 at. 42am. (59 modell) .y in Fig. 6. Fig. Sis a-plan view of the parts corresponding parts. t

In said above described views, a indicates a .suitable varnish or paintholding tank, which 69 as shown in Fig. 5, is preferably provided withaslopingportion a, which acts to directthe surface daub back into the tank. Said'tank or vataissu'itably secured between two standards or supporting frames 12 and b of the machine to which is secured at the op-Q' posite end of the machine any suitable form of armsv or brackets b and b on which is arranged a tilting table 1).

As will be seen from Figs. 1, 3.and 4, the drive-shaft c, which may be arranged in ad,- justable bearings b in the two frames b and -b is provided on the one end with a driving pulley c and on its opposite free end with a gearc which meshes with a pinion d arranged 7'5 1 l to rotate on the side of the one frame, as shown in said Fig.4. Meshing with said pinv ion (1 is a gear (1' and meshing with said gear (1' is a second gear (1 connected with axles d and d respectively and on which are arranged the feed rolls (2 and cl respectively,as clearly shown in Figs. 1 and 5. Said shaftsor-axles' d" and 01 may be arran ed in adjustable boxes" in said frames b and b and on said axles I can arrange shearing or punching devices, as will be more fully described hereinafter. (0n said shaft cbetween the two frames 1) and b,

is arranged'a carrying off roll 0 of metal and directly above the same, and; in line with the vertical axis of said roll 0 is a paint or var-, 9o nish feeding roll E arranged. on -a shaft e provided with a gear a which meshes with a gear c on the drive shaft 0. Said rollE is preferably made of caoutchouc and the shaft e arranged in suitable bearings b in the sides of 95 the frames b and b. Meshing with said gear eon the shaft e is another gear-wheel f on Y ,a shaft or axle f for driving a second caoutchouc rollF also arranged in adjustable bearings b", which bearings are capable of an up we of the same diameter and that they must have the same surface speed and therefore I have represented the gears c e, f and g all of the same size,but the diameters of the several feed rolls and the size of said gears may be.

varied if necessary. I

The operation of the machine is as follows:-- The power-shaft c, by means of the intermediately arranged system of gearing causes the feeding or pinching rolls d and d to retate in the direction of arrows, as indicated in Fig. 5, and rolls C. E, F and G rotate in the direction of the arrows, as indicated in said figure. The sheets of tin,- or other material to be varnished are placed upon the table 6 and inserted in front of the pinching rolls d and d from which they are fed between the carrying-off roll C and the feed roll E upon the carrying-off apron h, as will be seen from Fig. 5. Said apron is arranged on an axleh' having a pulley h and operated by'a belt h from a driving pulley c on the shaft 0. -When and" rotate, as indicated,.in' the direction of the several rolls-or cylinders are thus operated thearrows'in Fig.5, the paint or varnish is carried up from the tank or vat a. and evenly spread over its periphery by means of an adjustable scraper 'i which can be adjusted to permit a substantially thick or 'thin coating of aint or varnish on the surface of the roll, an this paint or varnish .is then distributed by contact to the"gum =roll F'and from this roll to the other gum roll E and thereby spread upon the sheet tin or other. material passed between. the rolls E and O. Said roll- 0 has in.

contact therewith anadjustable seraperj secured between the frames b and b, the scrap.- ing surface of which removes any paint or varnish that may have been brought upon the surface of the roll 0 and causesthe-paint or varnish to fall into a suitable-receptacle 7", as shown in- Fig. 5. It will be noticed that all the rolls except the roll G are arranged in adjustable'bearings whereby they can be brought farther apart or in very close proxi'mity= accordinglto the thickness of the coat-- of paint or varnish to be applied tothe mate .rial passing over the roll 0. e

As will be seen mor'e'especially from Figs, 9and 10, the adjustable scraper consists ess entially of a plate 6' to which the scraper 13 is secured. Said plate '17 is arranged onan adjustable bearing plate '7, all ofwhich are ar.

ranged on brackets b on the frames b and 'b' by means of the plates b and-the bolts b Said plates 1" and the bearing plate r? are adjustably held together by means of the bolts i which pass through elongated openings or holes in said ,plates, as illustrateddn Fig. '10. Near the front edge of the plate 2" I have arranged a series of screw threaded holes 71 in which are placed thumb screws 1' by means of which the scraper i, which is made of spring metal can be tightly forced against the surface of the roll orrelaxed therefrom to cause auniform thick or thincoating of paint or varnish to be distributedon the cylindrical surface of the roll G, as the case may-be.

As hereinbefore stated, in place of the rolls (1 and d, I may provide said axles or shafts d and d, with cutters or shearing washers and punching devices, as shown in Figs. 6 and 7. In said construction, the shaft (2 is provided at one endwith a screw-thread d and the shaft d with a'similarly arranged screwthread d These shafts or axles are arranged in their bearings in the frames b and b in the manner described herein above but, are provided with collars k and k of which the upper collar k' is slightly longer than the collar Said collars abut against the inner edges of the hearings in the frame of the machine and adjacent to said collars I arrange the cutters lon the shaft d and the cutters l on the upper-shaft d4 respectively; and then place by collars or'washers m, and, on the screw-threaded endsof the shafts may be another set'ef cutters which are held in place by suitable nuts nand n arranged on the 'screw thre'aded ends'of the shafts. Thus it will be seen, that any such number of shears or cutters can be suitably arranged on the axles or shafts, the intermediately arranged plain shaft d. The) construction of said collars 0 will be seen from the two sectional views of said collars, in-Figs.-6 and 7. Said collars are provided with an annular chamber 0 formed by the walls o 'and 0 see Fig. 6, and in these a suitable number of plain washers or collars m, when another setof cutters can be ar-' ranged on the shafts, which are also held in perforations 0' in a collar 0' on the opposite chambers I arrange a suitable number of spring-actuated guideso each provided with oneor morefingers 0 which extend into said perforations of, as clearly indicated in Fig. 7. Now, when the sheet metal passes between the two punching collars, the small pieces of metal will accumulate uponsaid fingers o and be retained in said erforations until the perforation reaches the lowest point during the revolutionof the shaft (1 and the metal pieces will then be forced from the perforations 0' by the spring-actuated guides o and drop beneath-the machine, as-will be clearly .understood. These forms' of rolls d and d are of great advantage in cutting the sheet metal-intopieces ofthe proper size and perforating the same when used for trunk tin, said holes being used-for the reception ofnails r securing the tin to the trunk body. .The primary advantage of myi'nvention, re. and also the principal object is to avoid any double handling of the sheet metal pieces, by

cutting the same and punchingthem and also. providing the pieces with the proper coating of paint or varnish. It is this feature of my :5 invention which I wish to claim broadly and which I deem of special importance. A It not a only reduces the time and 135th involved in applying the varnish, but every part of the sheet metal, on itsface, is painted or, var-. nished with equal facility and no waste is caused by the cutting of the sameinto sheets of the proper size. 7

The apron, for carrying off-the finished "pieces; may be made of canvas or any other 2 5 suitable material v i Havingthus described my invention, \v'hat I claim isv t e p 1. In a machine for coating sheet metal or other articles with paint or varnish, the com-. 5o bination, of a varnish or paint holding tank of the forn1"hereinspecified,a roll G arranged 'bination with an 4 -with punching pins Z and washers-m, thereon sheetto be. coated or painted. is passed, an' apron arranged behind said roll 0, a scraper and a-pair ofrolls E and 0, one above a the other, through which the in contact with'said l'OllgG, and a scraper in contact with said roll O, a pair of feeding rolls d and cl, a system of gearing for-open ating said rolls, a "pulleyc and a pulley 7L2 and belt h for operating said conveyer, all of said parts being arranged substantially as and for the purposes set forth.

2. In a machine for coating'sheet metal or other articles with paint or varnish, the-com-' axle d cutters 1 p ovided and an axle d perforations 0', pins 0, 1ar s par for purposes set forth.

, In testimony that I claim the inventionset forth above I have hereunto set my hand cutters land collars 0 having spring-actuated guides o andarranged in achamber o in snch'colo, of paint or varnish distributing rolls, a at or varnish tank, and actuating devices causing the rotation olsaid rolls, forthe this-14thday of March, 1892. 4 i HUGO I-I AEFNER.
